If a guest sees something bad, he should go back
حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا وَكِيعٌ، عَنْ هِشَامٍ الدَّسْتَوَائِيِّ، عَنْ قَتَادَةَ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ عَلِيٍّ، قَالَ صَنَعْتُ طَعَامًا فَدَعَوْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ فَجَاءَ فَرَأَى فِي الْبَيْتِ تَصَاوِيرَ فَرَجَعَ .
It was narrated that ‘Ali said: “I made some food and called the Messenger of Allah (ﷺ) (to come and eat). He came and saw some images in the house, so he went back.”
